MACHINE FOR BENDING SHIPS I-IOOKS.

Specification of Letters Patent No. 14,193, dated February 5, 1856.

To all whom t may concern:

Be it known that I, ELisHA HARRIS, of the city and county of Providenceand State of Rhode Island, have invented a new and useful Machine forBending Ship- Hooks, Which is also Applicable to the Bending of otherArticles of Similar Shape; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification, in which-Figure 1, is a. vertical section of the machine taken through theprincipal working parts and showing them in condition for commencing`the bending operation. Fig. 2, is a similar section of t-he principalworking parts but showing them in their condition after having finishedthe bending. Fig. 3, is an elevation of the machine as seen in adirection at right angles to Fig. l, the working parts being shownentire but the frame work of the machine in section.

Similar letters of reference indicate corresponding parts in the severalligures.

The machine which forms the subject of this invention consists of tworollers or the equivalents thereof, one of which has a portion of itsexternal form the counterpart of the intended form of the interior ofthe hook and is provided with a pocket in which the eye of the hook isreceived and secured during the bending operation, and the other has a.form corresponding' to the exterior of the hook, the said rollers beingconstructed arranged and operated as will be presently fully described.

A, A, are two rollers arranged parallel to each other in suitablebearings f, f, and geared together in such a manner as t-o be capable ofmaking any required portion of a revolution together. The lower rollerA, is that around which the hook is to be bent, and therefore is made ofthe intended forni of the interior of the hook as is illustrated in 2,where the finished hook is shown colored red. That I term the pocket ofthis roller consists of a bo-x B, cast on one side of the roller, (thewhole being of cast iron) and fitted with a sliding clamp C', which isformed with a circular boss a, a, at its end of a size to enter into theeye of the hook as shown in Fig. l, where the hook blank and the clampare both shown in section, the hook bla-nk being colored red. This clampis movable by a screw D, in such a manner as to allow the eye of thehook to be inserted in the box, and after it is inserted to secure it tothe bottom of the box. It is kept in place by a slot It, working on apin c, which is fixed in the box. The upper roller A, is employed tobend the hook blank around the lower roller, and for that purpose is ofsuch form as to confine the blank to the exterior surface of the rollerA. In order to prevent the upper roller A, from fiattening the blankunder the pressure necessary for the operation, its surface is groovedto suit the form of the blank.

The hook blank before being brought to this machine has been so forgedas only to require bending to make a finished hook. It is heated to asufficient degree and brought to the machine, the rollers being broughtto the position shown in Fig. 1, and the clamp C, unscrewed and drawn uphigh enough for the eye of the blank to be received in the pocket. Whenthe eye is placed in the pocket the clamp is brought down by the screwD, as shown in Fig. l, by which means the blank receives a slight bend,as shown in l. Power is then applied to turn the rollers about half arevolution by which means the hook is bent around the lower roller A, asshown in Fig. 2. After this has been effected the rolle-rs are turnedback again to the position shown in Fig. l, and the clan'ip C,unscrewed, to allow the hook to be drawn off the end 0f the roller A.This roller is tapered toward its end as shown in Fig. 8, to allow thehook to come off.

It may be here remarked that owing to the unnecessarily larger size ofthe roller A, it has a tendency during the bending operation to forceback the hook toward the pocket, by which means it is slackened on theroller A, and prevented hugging it closely and by that means the hook isenabled to be easily drawn off the latter roller when inished.

Vhat I claim as new in this machine and desire to secure by LettersPatent is- The roller or former A, of the intended form of the interiorof the hook provided with a pocket or clamp for securing the eye of thehook blank during the bending operation substantially as hereindescribed.

ELISHA HARRIS.
